My puppy is 2 months old and he has roundworms. I gave him deworming pills and now he won't eat at all. He didn't eat for a full day and now going on another day. He throws up at least every hour but he is still drinking lots of water. He is pooping out blood and a little bit of water sometimes. He has lost a bit of weight and looks like a skeleton. Please help me with some ideas on getting him to eat.
